sition while being nailed or otherwise se-V cured to the box.

An object of this invention is to provide a foot operatedl mechanism.Y of novel construction for clamping the lid upo-n citrus fruit 'boxes andthe like, and'novelmea-ns for. locking the device in its clamped position.

Another object of thisinvention is to pro-p vide novel means for releasing the clamping device after the cover has been securely nailed to the fruit box or container. Y

further object of this invention is .to provide a box pressing or clamping device of generally improved construction, whereby the device will be simple, durable 'and inexpensive in construction, as well as etlicient in its use.

l/ith the foregoing and other objects in vien7 which will appear as the description'rv proceeds, the invention resides inthe combi-y nation hereinafter described and claimed, it

being understood that changes in the precise i embodiment of the invention herein disclosed,'can be made within the scopeof what is claimed without departing of the invention. A Y

- rhe invention has been illustrated in its preferred embodiments in the accompanying drawings wherein z- Figure 1 is a front view of the device, parts being broken away.

2 is a plan view of the invention.

F 3 is a vertical sectional view of the device, showing it in its clamping or pressing position.

Fig. 4t is a similar view showing the device in its released position. Y

Referring to the drawing there is shown a frame comprising vertically disposed supports or legs 5, a box supporting platform or table 6 and spaced uprights 7. rlhis frame may be of any preferred construction and it is to be understood that the frame from the spirit herein: disclosed is only indicative of one formthat lmay be advantageously employedv in connection closed. y

Bearingplates S areprovided 'and have elongated slots`9 formed therein for the receptiony of Ybolts or other securing devices 10 which adjustably secure lthe plates 8 to bars 11 that are'slidablysecured to the up'- right 7 by means of straps or bearings 1,2.

with'the mechanism to be disy.

Toggle mechanismv areprovided and in-k Y journaledto the bearings 17 and these arms are rigidly secured Vto the arms l5 by mean's ofv braces or'straps19,thereby providing a f bell crank lever structure which operates v as a unit. Thel terminals of the short leverv arms 1S, which 'are remote from the bearings 17, are connected with the inner or'adjacent ends of theutoggleV links V13' A111 through the instrumentality of connecting' links 20.

Retractile springs 21 have their` upper terminals secured to theiupper terminals of standards7 by means of depending hooks 22 and the lower terminals of these springs are connected with the plate 8, by means of hooks orfother securing devices 23, which springs serve to normally hold ther bars 11 in their elevated position.

Vextend horizontally from the 'upper terminals of thesliding bars 11 toward the front of the machine.

A stop member or strip 25 is adjustably is adapted to limit the rearward movement of 'a fruit box B, tothereby properly position this box upon the table 6 in order that its cover or closure may be'engaged by the arms 24, as will be hereinafter disclosed.

Releasing levers 26 are pivotally secured to the frame as shown atV 27. The outer or front'terminal of the levers 26 are provided with foot treadles 28, while the inner or rear terminals 29 of the levers 26 lie in the path of travel of the lever 15 to operably engageV Gripping arms L soV ' secured 'to the upper face of the table 6 and the lever l5 during the operation of the device.

In operation the fruit Vbox is positioned upon the table 6- in engagement with the guide member and then the treadle end of the lever 15 is moved downwardly by the' foot of the operator, which causes the toggle mechanism to force the bars ll and arnlis 24: downwardly into engagement with the cover of the fruit box. Further downward movement of the lever l5 will cause the adjacent ends of the toggle links 13 and 11i to move past the dead cen-ter points and rest against the bar 1l or other stop means as indicated at 30. Now the cover member C has been forced into proper position upon the fruit box B and where it may be readily `nailed or otherwise secured to the box. The toggle mechanism may be readily released vby simply pressing on Vthe treadle 28 oi' one of the levers 26 which causes the end 29 of this lever toengage the lever l5 and move the toggle mechanism from its locked position,

which allows the retractilev springs 21 to raise the sliding bars l1 vand arms 24, thereby releasing the box. The fruit box may now be removed and another placed upon the table and the above described operation may be repeated. f y

Having thus described'my invention,l what I claim isfn f Y l. A device of the class described .including a frame comprising a table and an upright, a composite bell crank lever journaled to the said frame, a bar slid'ably secured to the-said upright, a gripping arm. carried by the said bar, a toggle mechanism operably connected with the frame and the sliding bar, a link operably connecting the toggle mechanism and the saidA bell crank. lever in order to allow the saidbell crank lever and toggle mechanism to slide the arm l1 downwardly toV aV locked position, a retractile spring having one terminal secured to the saidv sliding bar and the opposed terminal secured to the upright and adapted to slide the said bar upwardly, and means for engaging the bell Crank lever and releasing it from the locked position. V

2'. uA device of the class described including Va frame comprising a table and an upright, a bar slidably secured to the said upright, a toggle mechanism operably connected to the lower terminal of the bar andl to the said frame, a gripping arm carried by the sliding bar, and adapted to'engage the cover member of a fruit box, a link having one terminal connected to the toggle mechanism, a composite bell crank leverl ournaled to the frame and operably connected with the link to thereby move the toggle mechanism past a dead center to a locking position, a lever pivotally secured to the said vframe having one terminal in the path of travel oi' the bell crank lever and adapted to engage the said bell crank lever to release the bell crank lever from its locking position, a retractile spring having one terminal secured' to the upright and the opposed 'terminal ad-V justably connected to the sliding bar, and

adapted to normally hold the said bar in its upright position.`

B. A device of the class described including a vframe comprising a table and an up right, said table adapted to support a container, a guide strip adjustably secured to the table and adapted to limit the movement of the containerl upon the said table, a bar slidably secured to the said upright, a gripping arm extending perpendicularly from the upper terminal of the said bar. and

adapted to engage the cover member of the v Y.

normally support the sliding bar inV anelevated position.

In testimony that I claim the 'foregoing as my own, l have hereto aiiixed my signature in the presence of two witnesses. Y
